Neither grip is weather sealed to my knowledge. The gap between the grip and body would allow moisture to hit the grip-to-body electronic contacts, and there's no rubber gasket around that.
i bought the grip, its not weather sealed like the MB-D10. Quality feels about the same as the Nikon counter part. So if a $0.30 gasket to keep out water is worth the extra $150, this grip isn't for you.
If you dont really care about the gasket, this grip is for you, sorry nikon.

Which im working on now, was we speak, lol.
Custom weather sealing for the win!
*edit*
also forgot to mention the zeikos grip has a half-way autofocus and then a full click for the shutter button, as opposed to the MB-D10 which was overly sensitive IMO

didn't want to bump the thread, but this grip is crap compared to the MB-D10. 2nd day of owning it, the battery tray got stuck inside the compartment. Had to forcefully pull it out, which in turn bent a little prong on the AA holder, now it gets stuck all the time. The AA battery tray is a nightmare for batteries, the MB-D10 is a snug fit, this thing will make your fingers hurt putting batteries in.
Its on its way back to BH.
For 1/3rd the price, you get 1/3rd the quality. MB-D10 is the way to go, for me atleast.
I've ordered one today from B&H, should be here Tuesday along with another EN-EL3e battery. Had to phone it in since I was using a card I got for a rebate, along with another CC. Price is back down to 64.95 and free shipping.
I have the Zeikos on my D700 and really like it.
With the 8 AA's the D700 is super fast, but I use it empty as well, for the extra buttons and the better feeling balance.
You can program the extra AF-ON button on the grip as another Function type button, this was one of the main reasons I bought it. I have it set to AE-Lock, as my main AE-Lock button is set to FV-Lock
